Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 163974, here are decompositions:
- 47 + 163927 = 163974
- 73 + 163901 = 163974
- 103 + 163871 = 163974
- 113 + 163861 = 163974
- 127 + 163847 = 163974
- 163 + 163811 = 163974
- 193 + 163781 = 163974
- 233 + 163741 = 163974
Showing the first eight; more decompositions exist.
